If anyone's curious about what they've changed, here is all of the changes I've noticed so far. Haven't played too much, so there's probably more.
Added the Heartlands, which by the way, is massive compared to all the other areas they've added. It also has a small village with NPCs. They might add more stuff in future updates, but I can't say for sure.
Completely revamped the character creation
Dog eggs? (I've boxed it in red, in case you couldn't find it) Edit: If you put it in you hotbar and click on it, you get a pet dog
Also, no more butt-scooting bug, sadly. Edit: I recently saw people doing this in SCC, so it's actually not out yet. I just haven't figured out how to do it.
Again, this is only the stuff I've noticed so far, and since I've only played for an hour or two, there's probably some more things that I haven't seen.
